I can't speak for others--but in my case, "obsession" with the bass stems from:
-- deep familiarity with all manner of live music performed in actual music spaces (everything from rock to jazz/jazz clubs to opera to large symphonic and/or choral works in concert halls)
-- Speaking of the symphonic/choral music (because it's non-amplified), there is a huge weight & dynamic capability from the lower midrange on down that completely envelops the listener. Mid-bass and deeper bass is felt as much as heard
-- In electrified settings, the bass is also larger & more dynamic than most other things. It can get downright concussive, depending on the mix, the amp, and the player
So when setting up home audio or desktop audio systems, I look for at least a convincing simulation of that natural bass weight/impact. And that means messing with subs. More than just subs--it also means choosing speakers that are capable of that natural bass weight/impact from the midrange on down.
In short, it's not "obsession" as much as pursuit of what one hears in real life music.
